Blake Lively (Serena) has been one busy bee since getting married to her new hubby, Ryan Reynolds. Between looking amazing, carrying around that enormous rock otherwise known as her wedding ring, and filming Gossip Girl, it's a wonder she had time to attend Amber Tamblyn's wedding to David Cross!But you guys, The Sisterhood. The Sisterhood of the Traveling Pants trumps everything, and there was no way Blake would consider missing her co-star Amber's wedding. In fact, America Ferrera and Rory Gilmore Alexis Bledel were also in attendance. It's the pants, guys, they brought them together –– sob!Before you tailspin into a fit of feel-goodery and denim, check out this adorable photo of Ryan and Blake at Amber's outdoor wedding.
